fish population
Lake's swimming count
Fish population refers to the total number of fish of a particular species living in a defined area—a lake, river, reef, or ocean region.
Biologists track fish populations to assess ecosystem health and set sustainable catch limits.
The term appears in conservation contexts: The salmon population has declined by forty percent.
It can also refer collectively to all fish species in an area: Pollution has devastated the bay's fish population.
